Abstract

A device for cooling batteries includes a cooling plate for receiving at least one battery thereon and at least one heat transfer element in heat transfer relationship with the cooling plate. A mechanical stress produced by a contact force causes the at least one heat transfer element to thermally abut the cooling plate.

First claim

What is claimed is:

1. A device for cooling a battery of a motor vehicle, comprising:
a cooling plate having a top surface contacting an entire bottom surface of the battery;
a plurality of flexible cooling hoses contacting a bottom surface of the cooling plate; and
a plurality of leveling-out elements supporting the flexible cooling hoses, wherein each of the flexible cooling hoses is provided between the cooling plate and a respective one of the leveling-out elements wherein the flexible cooling hoses thermally abut the cooling plate under mechanical stress produced by the leveling-out elements,
wherein the leveling-out elements are at least one of a hydraulically acting element, a gel cushion, a water bed, and a polymer material with resilient properties.

2. The device according to claim 1 , wherein the flexible cooling hoses are disposed between the cooling plate and the leveling-out elements to apply a contact force to the cooling plate.

3. The device according to claim 1 , wherein the flexible cooling hoses are configured as a hybrid hose with a vulcanized-in cooling plate.

4. The device according to claim 1 , wherein the flexible cooling hoses are affixed to the cooling plate by a fastening means.

5. The device according to claim 4 , wherein the fastening mean is a bolt.

6. The device according to claim 1 , wherein the flexible cooling hoses are adhesively bonded to the cooling plate.

7. The device according to claim 1 , wherein the flexible cooling hoses are disposed between the cooling plate and at least one of a battery casing bottom and a supporting plate.

8. The device according to claim 7 , wherein the battery casing bottom includes a raised border to guide the flexible cooling hoses.

9. The device according to claim 7 , wherein the supporting plate includes at least one groove-like recess to guide the flexible cooling hoses.

10. The device according to claim 1 , wherein the cooling plate is received in a frame provided with a clip element.
